Armed police have been deployed to patrol university and college campuses in the northern English city of Bradford.

The armed officers were deployed following the suicide attack at a concert in Manchester that killed 22 people on Monday.

Emails sent to all students at Bradford University said that two armed officers would be patrolling the university's city campus and Bradford College situated in the same area.

The email urged students to not be "alarmed" at the presence of armed officers on its campus and that the police were present to "provide reassurance".

Many people are staying away from campus because of the armed guards

Students were also asked by the university to "remain vigilant but not alarmed" and to contact the university if it had any security concerns.

The deployment of armed officers comes after the UK's threat level was raised to "critical" by British Prime Minister Theresa May on Tuesday.

Muzzamil Khan, president of Bradford College Students' Union, told Middle East Eye that he was not against armed guards being on campus but that many students felt "intimidated" by the presence of the police.

"Many people are staying away from campus because of the armed guards and not wanting to talk about anything," Khan told MEE.

"Why are there heavily armed officers outside an institution where 80 percent of the student body are from a BME background," said Khan. "It's not justifiable that they are standing outside one institution and not other institutions in Bradford."

A spokesperson for Bradford University confirmed to MEE that armed officers were being deployed to patrol the city as part of "upgraded security measures across the country".

Armed police officers were also deployed to guard parts of Bradford's city centre and council buildings.

Kersten England, chief executive of Bradford Council, told the Telegraph and Argus that the "measures have been taken in light of the ongoing critical threat level."

Large numbers of armed officers were also placed at Leeds Bradford airport and at an international cricket match in Headingley after the terror attack in Manchester on Monday.
